That’s how Mayor Giuliani and Conservative Party boss Mike Long were on primary night.

At the festive Midtown victory party for George W. Bush, Giuliani and Long brushed right past each other without so much as a nod or a hello.

“I guess he didn’t see me,” Long said later. “Who knows?”

A possible Conservative and Republican challenger to Rudy, Rep. Rick Lazio (R-L.I.), was a no-show at the Bush bash, although many had expected him.

But Long said he’s got a Senate candidate ready to go and plans to

promote the still-anonymous person at the Conservative Party convention later this year.

Since announcing her candidacy last month, Hillary Rodham Clinton has been trying to spend as much time as she can in New York — but she’s not exactly a full-time resident.

Campaign Buzz has determined that, including tonight, the first lady has slept 20 out of the 34 nights somewhere in New York — or just under 60 percent — since she formally threw her hat into the ring on Feb. 6.

Her other overnights have been in the White House, except for an evening she spent in Chicago after a fund-raiser.

It could not be determined how many nights she has spent at her new home in Chappaqua.
